C# GrdiView需要1个DataKeyName用于1个方法，2个DataKeyName用于另一个方法

嗨，我的GridView有问题。我有一个方法需要两个DataKeyName，然后还有一个方法需要一个DataKeyName。我不知道该怎么处理？谁能告诉我该怎么办？我将在下面发布我的GridView代码。如果需要其他代码，请告诉我。谢谢

    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="ObjectDataSource1" DataKeyNames="intExaminerID,sintDOLDistrictOfficeID" OnRowCommand="GridView1_RowCommand">
        <Columns>

                    <asp:TextBox ID="txtID" Visible="false" runat="server" Text='<%# Bind("intExaminerID") %>'></asp:TextBox>

问题可能是您想使用密钥的方法有点不清楚，但您可以使用它们的名称来获取密钥，如：

//rowindex is the index of the row you want to get the keys for
string intExaminerID= GridView1.DataKeys[rowindex].Values["intExaminerID"].ToString();
string sintDOLDistrictOfficeID= GridView1.DataKeys[rowindex].Values["sintDOLDistrictOfficeID"].ToString();
